HARRY J. FORD, 015 SAN QUENTIN, CALIFORNIA, ASSIGNOR F ONE-HALF TO WILLIAM I JOE N HILL.

ELECTROMAGNETIC ENGINE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, H RRY J. Form, a citizen of the United States, residing at San Quentin, 'inthe county of Marin and State of California, haveinvented new and useful Improvements in Electromagnetic Engines, of which the following is a specification.

The'present invention provides a moto utilizing electricity as the motive force, the

purpose being to devise an engine which.

may be used for a variety of purposes where small and effective engines are requlred both for the sake of lightness and to econo- -mize space;

The invention consists of the novel features, details of construction and combination of parts, which hereinafter W111 be the accompanying drawing, and pointed out in the'appended claims. I

Referring to the drawing, forming a part of the specification, Figure 1 is a plan view of an electric engine embodying the invention, one of thesolenoids being in section. Fig. 2 is a front view of the commutator.

The engine comprises a crank shaft B having its crank portion set quartermg, said crank shaft being mounted in any suitable manner and provided with a fly wheel G andv a bevel pinion H. A plurality of solenoids A, A A and A. are ar ranged in series and are coupled to the crank portions of the crank shaft and are adapted to beienergized in successive order to a ply the force to the best possible advantage for driving the crank shaft. The solenoids are suitably mounted and are fined. Blocks E receive straps F which are passed about the solenoids and serve to secure them to the said blocks. A steel plate L is located atv one end of each solenoid and when charged acts in the capacity of a mag: net to assist materially inactuating the core of the solenoid. Each solenoid has a core E, which is in the nature of a plunger and has a rod C attached thereto, said rod being connected by means of a pit-man D with a crank of the shaft B. A shaft J is arranged at a right angle to the shaft 13 and is provided with a gear wheel I, which is in mesh with thepinion H. The gear wheell is about four times the diameter of the pinion H so that when the shaft B the commutator is attached to the shaft J Patented Feb. 20, 1912. Application filed May 6, 1911. Serial No. 625,472.

and consists of an arm 0, which is arranged solenoid and four groups being provided upon the disk or plate K so that during one.

revolution of the shaft J the solenoids are energized four times. The control is indicated at X and may be of any construction or make. Wires V connect the control with the source of electric supply which in the present instance is indicated at WV and constitutes a storage battery. A wire I connects the control with one terminaLof each of the helices or windings of the solenoids. "Wires P, Q, R and S connect the other terminal of the helices or windings of the respective solenoids with the contacts 1, 2,

3 and 4 of the respective groups of contacts a arranged upon the plate or disk K. A wire I connects the other terminal of the control with the annular contact I) of the commutator. In the operation of the engine the shaft J has a rotary movement imparted thereto which causes the outer end of the arm 0 to sweep over the contacts 6 and a so as to successively close the circuits including the solenoids, whereby the latter are energized in rotation, thereby attracting the cores E and imparting i -tary movement to the shaft B. The shaft J- may be mounted in any manner and isshown stepped in 'abearing to which is fitted an From the foregoingdescription, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to Which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the embodiment thereof, I desire tohave it understood that the device shown is merely illustrative, and that such changes may be made when desired as are Within the scope of the claims appended hereto. v
